Document Summary

After the animal dies the blood is removed and there is no oxygen being delivered to the tissues anymore. This means that in addition to no oxygen there is also no glucose. The process of slaughter: sunning: by either physical, chemical or electrical means, exsanguination: this is the removal of the blood. It removes about 50% of the blood since some still remains in the narrow capillaries. The blood pressure drops and causes the increase in heart action and contraction of vessels. When the amount of blood becomes insufficient the circulatory system will fail. When blood gets low we get a switch from the oxidative phosphorylation pathway and then we go to the glycolytic because we have no oxygen: rigor sets in. Rigor, the stiffening and loss of extensibility in muscle when the sliding mechanism between myosin and actin no longer functions because there is no more energy in the muscle.
